What is ground resolution?

Ground resolution refers to the smallest discernible detail that can be resolved in an image captured by a remote sensing system, such as a satellite or aerial camera. It is typically expressed in terms of the area on the ground represented by one pixel in the image. Higher ground resolution indicates more detailed images, allowing for better identification of features, while lower resolution may result in a loss of detail. It is a critical factor in applications such as mapping, environmental monitoring, and urban planning.
